Dear all, While rewriting part of sage.rings.arith I modified the behavior of the binomial functions with respect to the output type (see #17852):
old version (sage-6.5): sage: type(binomial(4/1, 2)) <type 'sage.rings.integer.Integer'> sage: type(binomial(4, 2/1)) <type 'sage.rings.integer.Integer'> new version (#17852): sage: type(binomial(4/1,2)) <type 'sage.rings.rational.Rational'> sage: type(binomial(4,2/1)) <type 'sage.rings.rational.Rational'> This is just an example and actually plenty of output types are now correctly handled. As a consequence of this, there is a failing doctest in multi_polynomial_ideal in the function random_element! I figured that the .basis() method of ideals does not return the same thing in both versions. I am not familiar at all with that code (which is very dirty by the way). So if somebody cares to debug, please have a look. Otherwise, I just used a trivial fix that amounts to change the output in a doctest. I am quite sure that something is broken and already spent several hours trying to see what may have happened.
